Answer:

The relationship is linear.

Step-by-step explanation:

A linear relationship is a trend in the data that can be modeled using a straight line, such that a relationship between two variables x and y is linear if the rate of change is constant. That is, whenever x increases by 1, and it always increases by the same constant.

The constant by which y increases as x increases by 1 is called the slope and is denoted by the letter m. Being b the y-intercept, the linear relationship is modeled by the expression:

y=m*x + b

In this case x represents the minutes and y is the total number of pieces put together, so that each time x (minutes) increases by 1, "y" increases by 5 pieces. So knowing that you have already collected 253 pieces, the expression of the linear relationship is:

y=5*x + 253

The relationship is linear.

The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be repres
rusak2 [61]

Answer:

h(x) = 80x^2 + 560x

Step-by-step explanation:

To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):

h(x) = f(x) * g(x)

h(x) = 80x * (x+7)

h(x) = 80x*x + 80x*7

h(x) = 80x^2 + 560x

So the function that represents the total number of seats is:

h(x) = 80x^2 + 560x
